RELATIONSHIP BETWEEN SICKLE CELL NEPHROPATHY AND SOME BIOCHEMICAL MARKERS OF HAEMOLYSIS AMONGST PATIENTS WITH SICKLE CELL ANAEMIA IN KANO, NORTHWESTERN NIGERIA

Introduction

Advancements in the care of patients with sickle cell anaemia have led to significant improvement in survival with many patients reaching adulthood. As they age, long-term complications of the disease manifest in them, notable amongst which is nephropathy which is one of the leading causes of morbidity and mortality in them. There is limited information about sickle cell nephropathy and some biochemical markers of haemolysis that can detect it early in our setting. This study aimed to determine the relationship between some indirect markers of haemolysis and sickle cell nephropathy.

Methodology

The study was a descriptive cross-sectional one where 204 adolescent and adult patients with sickle cell anaemia attending the clinic of AKTH Kano were recruited. An interviewer-administered questionnaire was utilized. Blood samples were taken for determination of serum bilirubin, LDH, and reticulocyte count. Spot urine was used to quantitatively determine albumin to creatinine ratio. Data collated was analyzed using SPSS version 22.0. P-value <0.05 was considered significant.

Result

Two hundred and four (204) participants were enrolled in to the study. Their mean age was 19.6±5years. Females were the majority 131/204 (64.2%). The median (IQR) serum lactate dehydrogenase, bilirubin, direct bilirubin, and reticulocyte count were 607.0(487.3-758.5) U/L, 54.5(37.0-119.0) umol/L, 16.0(11.3-29.0) umol/L and 4.0(3.0-8.4%) respectively. Sickle cell nephropathy was found in 29/204 (14.2%). There were positive significant associations between sickle cell nephropathy with raised serum bilirubin and serum lactate dehydrogenase (p-value = 0.02 and 0.032 respectively).

Conclusion

Sickle cell nephropathy is common amongst patients with sickle cell anaemia and raised serum bilirubin and lactate dehydrogenase are predictors of sickle cell nephropathy.

Diagnostic usefulness of serum procalcitonin in patients with bacterial sepsis

Background

The Sequential Organ Failure Assessment (SOFA) score is used for the diagnosis of sepsis and involves clinical and laboratory parameters that may not be readily and/or timely available in most resource-poor settings. Procalcitonin (PCT) has its level changed in response to bacterial sepsis and its measurement costs only a fraction of the total cost of investigations required to calculate SOFA score. This study aims to determine the diagnostic usefulness of PCT in bacterial sepsis.

Materials and Methods

Ninety-nine participants were studied, divided into three groups: apparently healthy volunteers, those with bacterial infection without sepsis (SOFA score <2), and patients with bacterial sepsis (positive culture and SOFA ≥2). PCT level of each participant was measured and median group levels compared. Pearson's correlation was used to determine the correlation between serum PCT levels and SOFA scores in the sepsis group using a significance level of 5 percent (P < 0.05). Diagnostic usefulness of PCT was assessed using receiver operating characteristic (ROC).

Result

Positive correlation was found between serum PCT levels and SOFA scores among patients with sepsis r = 0.42, P = 0.016. At a concentration of ≥4.25 ng/ml, serum PCT as a surrogate for SOFA score had a sensitivity and specificity of 57.60% and 84.80%, respectively, for indicating sepsis. The area under the ROC curve (AUC) was 0.74 (95% CI {0.62 to 0.86}, P = 0.001).

Conclusion

Serum PCT concentration was significantly higher in bacterial sepsis compared to bacterial infection without sepsis and healthy state. PCT concentration demonstrated positive correlation with SOFA score in bacterial sepsis and can be used as surrogate for sepsis screening/monitoring in resource-poor settings.

Ethnobotanical study of medicinal plants used by the Kenyah community of Borneo

ETHNOPHARMACOLOGICAL RELEVANCE

Sarawak is located in one of the world's most biodiverse regions and is home to more than 40 sub-ethnic groups that each have their own distinct culture, language and lifestyle. This has given rise to numerous, unique ethnobotanical systems. However, due to rapid urbanization, this traditional knowledge is at a risk of extinction. Yet, ethnobotanical studies in Sarawak are almost non-existent, especially among Orang Ulu communities like the Kenyah.

AIM OF STUDY

Therefore, this study was conducted to document the ethnomedicinal knowledge of the Kenyah community. The main objectives of this study are: 1) To determine and document the diversity of medicinal plants used by the Kenyah community, 2) To determine whether the availability of modern medicine has affected Kenyah traditional medicine, and 3) To identify plants which have not been previously cited or used for previously unreported medical uses.

MATERIALS AND METHODS

We conducted repeated interviews and field surveys at the Asap-Koyan Resettlement Area, Belaga Sarawak. A total of 24 respondents from four Kenyah longhouses were interviewed in this study. Individuals possessing extensive traditional medicinal knowledge were identified via preliminary interviews or by viva voce. Translators were employed to ensure that there was no miscommunication. The results were evaluated based on the plant's total use-reports and number of respondents citing the plant. The data was also evaluated based on use-reports by ailment category.

RESULTS

Over 95% of the respondents were 40 years and older (58.21 years old ± 11.21). This was due to the younger members of the community (40 years old and below) admitting that they had almost no knowledge regarding traditional medicine, as they preferred relying on modern medicine. A total of 61 plant species were mentioned by the 24 respondents Seven plants had five or more respondents citing it, which was more than 20% of the respondents. These plants were Piper betle, Homalomena cordata, Senna alata, Annona muricata, Derris elliptica, Blumea balsamifera and Coscinium fenestratum.

CONCLUSION

Almost all of the cited plants had been previously recorded to be used in either Ayurvedic, Chinese herbal medicine, Malay traditional medicine or other Asian ethnomedicinal systems. However, there were four highly cited species that were used for treatments that were scarcely reported in past literature. These were piper betle (used by Kenyah to treat fever), Sauropus andrognus (used by Kenyah to treat fever), Derris elliptica (used by Kenyah to treat fever and influenza) and Coscinuim fenestratum (used by Kenyah to treat toxic effects from non-medical substances).

Addressing psychosocial issues caused by the COVID-19 lockdown: Can urban greeneries help?

The Coronavirus disease-2019 (COVID-19) pandemic has affected over 200 countries, forcing governments to impose lockdowns to contain the spread of the disease. Although effective in reducing infection rates, the lockdowns have also resulted in a severe negative impact on mental health throughout the world; Setting the foundation for mental illnesses to become the next "silent" pandemic. This study attempts to determine a self-care method of ensuring mental health during the COVID-19 pandemic, especially for those living under lockdown. We evaluated the potential of physical exercise (in a nature setting) and nature therapy in improving mental wellbeing, among young adults with either stress, anxiety or depression symptoms. The study involved thirty subjects, who were equally divided into a nature-exercise group and a nature therapy group. The participants were briefed on the activities that they were to perform on a daily basis, and both groups performed their assigned activities concurrently for one week (27th April 2020 to 3rd May 2020) at urban greeneries accessible to them (rooftop parks, neighbourhood parks, home gardens). We used the depression, anxiety and stress scale - 21 items (DASS-21) to evaluate the mental health status of participants, once before beginning the study (baseline readings) and once at the end of the study (after a week of nature-exercise/nature therapy). There was a statistically significant reduction in stress, anxiety and depression symptoms for both the nature-exercise and nature therapy groups. However, when evaluating the effectiveness of exercise and nature therapy in treating stress, anxiety and depression symptoms on a case-by-case basis, it was discovered that nature therapy was more effective in treating mental health issues. Hence, nature therapy has the potential to be a form of preventive medicine, namely in preserving mental health during the COVID-19 crisis.

Osmotic demyelination syndrome following acute kidney injury with hypernatremia

Osmotic demyelination syndrome (ODS) is a life-threatening neurological condition often associated with rapid correction of hyponatremia. While ODS is thought to be rare, with prevalence rates of not more than 0.5% in autopsy series, mortality rates are as high as 90% in some studies. Thus, timely diagnosis and life-saving treatment rest on a high index of suspicion among clinicians. In this report, we discuss the case and literature review of a 45-year-old female with sepsis, acute kidney injury, and spontaneous hypernatremia who developed ODS but responded to therapy with high dose steroids, antibiotics, and supportive care.

BLOOD PRESSURE CONTROL AMONG HYPERTENSIVE SUBJECTS IN DUTSE, NORTHWESTERN NIGERIA

AIM

Background: High blood pressure is an independent risk factor for cerebrovascular, renal and cardiovascular disease. According to World Health Organization treatment to target Blood Pressure (BP) of <140/90 mmHg has been associated with decrease in morbidity and mortality. Despite this BP control has been very poor even in developed economies.

OBJECTIVE

We set to assess level of BP control among hypertensive patients on treatment in Dutse, Jigawa state, and to identify treatable causes of failure to achieve target for better management.

METHODS

It is a cross sectional study of all hypertensives for more than one year attending medical out patients clinic who have consented. An interviewer administered questionnaire was used to obtain information from the patients.

RESULTS

A total of 123 patients of which 45% were females with mean age, duration of hypertension of 51.9 and 5.9 years respectively and BMI of 40.9Kg/ m². Eighty-three per cent, 91% and 94% were aware of salt restriction, cessation of smoking and alcohol moderation as lifestyle modifications respectively. The mean Systolic and Diastolic BP were 142mmHg and 86mmHg respectively. Fifty-two per cent were on two drugs combination including a diuretic while 4.87% were on three drugs or more. Less than a third (27.6%) had their BP controlled at <140/90mmHg. There was no significant difference in the demographic and clinical data between patients with controlled and uncontrolled BP.

CONCLUSION

This study found that control of BP is still poor in our setting. This could be due to physician inertia in the treatment, use of inappropriate combination of anti hypertensives or failure to reinforce lifestyle modifications.

MULTIBAND MILLIMETER WAVE T-SHAPED ANTENNA WITH OPTIMIZED PATCH PARAMETER USING PARTICLE SWARM OPTIMIZATION

This paper proposed a simple T-shaped patch antenna for millimeter waveband frequency operation. Millimeter wave is a frequency ranges between 30GHz to 300GHz in an electromagnetic spectrum. The proposed antenna consists of T-shape radiating patch mounted on rectangular substrate (FR4-4) and microstrip line for antenna feeding. An evolutionary algorithm called particle swarm optimization was used to optimize the length and width of the proposed antenna patch. The proposed antenna gives triple bands with central frequencies at 42GHz, 51.5GHz and 60GHz. The antenna offers minimum return loss of -19db, -24db and -19.5db at 42GHz, 51.5GHz and 60GHz respectively. The return loss impedance bandwidth of 5GHz for the first band, 8.4GHz for the second band and 5GHz for the third band was obtained. The proposed antenna was analyzed using Ansoft High Frequency Structure Simulator (HFSS) and MATLAB 2013. Radiation characteristics of this patch antenna are observed at various resonating frequencies.  http://dx.doi.org/10.4314/njt.v36i3.33

Prevlaence of chronic kidney disease markers in Kumbotso rural Northern Nigeria

BACKGROUND

Data- on the epidemiology of Chronic Kidney Disease (CKD) from sub-SaharanAfrica are sparse. We investigated the prevalence of CKD and its early markers in Kumbotso, a rural community in northern Nigeria.

METHODS

A total of 480 individuals were randomly selected from the general population using multistage stratified random sampling. Relevant- demographic and clinical data were obtained using a structured questionnaire. Biological samples (urine and blood) were drawn for relevant investigations.

RESULTS

CKD (estimated glomerular filtration rate [eGFR <60 mls/min) was found in 117 participants (26%). Proteinuria was present in 106 persons (23.6%) and haematuria in 7 individuals (1.6%). The most common CKD stage was stage 1 (20%). CKD was associated with hypertension (P=0.002), diabetes (P=0.001), high cholesterol (P=0.030), smoking (P=0.015), increasing BMI (P=0.020), and increasing age (P=0.003). After adjusting for potential confounding with logistic regression modeling we found BMI, family history of hypertension, history of diabetes mellitus and family history of renal disease to be independent predictors of CKD.

CONCLUSIONS

Early markers of CKD are common among rural inhabitants of northern Nigeria and this call for concerted efforts towards institution of preventive measures.

Evaluation of copper bioaccumulation and translocation in Jatropha curcas grown in a contaminated soil

Contamination of soils with copper (Cu) has become a serious problem in the environment. Phytoremediation is an emerging green technology that uses green plants to remediate heavy metal contaminated areas. This study was conducted to evaluate the potential of Jatropha curcasfor remediation of soils contaminated with Cu. Seedlings were planted in soils spiked with Cu in amount of 0, 50, 100, 200, 300, and 400 mg kg(-1) (Cu0, Cu50, Cu100, Cu200, Cu300, and Cu400) for a period of five months. The maximum height and number of leaves were recorded in control (Cu0) whereas the highest basal stem diameter was found in seedlings exposed to Cu50. Copper concentrations among plant parts were in the following trend: roots > stems > leaves. The highest total Cu concentration (665 +/- 1 mg kg(-1)) and total Cu removal (1.2 +/- 0.2%) based on total plant dry biomass were found in Cu400 and Cu50 treatments, respectively. J. curcas exhibited high root concentration factor (RCF > 1) and low translocation factor (TF < 1). Although Cu accumulation by the plant didn't reach the criteria of Cu hyperaccumulators, this species showed a potential to be used in phytostabilization of mildly Cu contaminated areas. However, the plant cannot be used for phytoextraction of Cu-contaminated soils.

Living kidney donor transplants over a 16-year period in South Africa: a single center experience

BACKGROUND

Kidney transplantation is the treatment of choice for end-stage renal disease (ESRD). The number of patients on the waiting list is increasing due to an imbalance between organ supply and demand. This has led to an increase in the number of living donor transplants in most parts of the world. The benefits to the recipients must, however, be weighed against the risks to the donors. Long-term follow-up of the donors is therefore imperative to ascertain the risks of living kidney donation.

MATERIALS AND METHODS

We reviewed the records of 571 potential living kidney donors (PLDs) in Johannesburg hospital over a 16-year period between 1990 and 2005.

RESULTS

There were 1030 kidney transplants during this period, with 800 cadaveric and 230 actual living donor (ALD) transplants. There were 571 PLDs; however, 341 (59.7%) withdrew or were withdrawn because of medical and non-medical reasons. Among the 230 ALDs, the mean age of the donors was 35.2 ± 8.3 years; 55% were females; 24% were Blacks. Eighty-five percent were related to the recipients while 15% were unrelated. Mean duration of follow-up was 8.6 ± 6.4 years. The pattern of post-donation follow-up was excellent in 29.7%, adequate in 34% and unacceptable/poor in 36.3%, based on the number of clinic visits post-donation. Hypertension was noted in 24% of the donors during long-term follow-up. Three of the donors also developed significant microalbuminuria.

CONCLUSION

There is a need to encourage living kidney donation, especially amongst the Black populations, and to emphasize the value and significance of post-donation follow-up visits to all potential donors.

Proteinuria among adult sickle cell anemia patients in Nigeria

BACKGROUND/OBJECTIVE

The life expectancy of patients with sickle cell anemia (SCA) has improved with modern medical care, and this has led to frequent observation of various chronic complications of the disease including abnormalities in renal function. Proteinuria is not only a marker of renal disease but is also a predictor of disease progression. This screening study was aimed at evaluating the prevalence of proteinuria among adult SCA patients in Kano, Nigeria, which has not been reported previously.

MATERIAL AND METHODS

A total of 200 adult SCA patients were studied. They consisted of 100 men and 100 women. Blood was collected for the assay of serum urea, sodium, potassium, chloride, bicarbonate, and creatinine and estimated glomerular filtration rate (eGFR) was determined using the Cockcroft-Gault formula. Urine dipstick test for the presence of proteinuria and other abnormalities was done, and 24-hour urine protein was measured in those with significant proteinuria.

RESULTS

Mean age of the male patients was 25.1 ± 1.0 years, whereas the mean age of the female patients was 22.8 ± 4.2 years. Twenty eight percent (32 males, 24 females) of the subjects were observed to have significant proteinuria. The mean estimated eGFR of the males was 88 ± 19.6 ml/min while that of the females was 92 ± 10.2 ml/min. The male SCA patients with proteinuria had a mean eGFR of 70 ± 6.9 ml/min, whereas the female SCA patients with proteinuria had mean eGFR of 101 ± 2.5 ml/min. Among the male patients with proteinuria, 50% had chronic kidney disease (CKD).

CONCLUSION

Proteinuria which is a marker of renal insufficiency is common among adult SCA patients, and routine screening for proteinuria may help detect those at increased risk of renal disease. CKD prevalence is high among SCA patients with significant proteinuria.

A report of three consecutive pregnancies in a kidney transplant recipient and the challenges in their management in a poor resource setting

Kidney transplant recipients (KTR) have a good outcome of pregnancies. However the mother and the child are increasingly at higher risks of complications compared to the general population. The management of these pregnancies is associated with greater challenges and is better if managed by both the obstetrician and the transplant physician. Kidney transplant is available in few centres in Nigeria and the post transplant population is increasing, but to our knowledge no report on pregnancy management in KTR has been published. We present a 25 years old Nigerian who had a live related kidney transplant and later had 3 consecutive pregnancies and review the relevant literature. She was placed on oral contraceptive pills for 2 years after transplantation. She enjoyed a stable allograft function with no rejection episode, no proteinuria, had a good blood pressure control and pelvic ultrasound scan was essentially normal. She conceived her first pregnancy 26 months post transplant however she developed spontaneous abortion at 3 months gestation. She conceived her second pregnancy 33 months post transplant which was supervised by the obstetrician and the transplant physician. She had complications including urinary tract infection, anaemia and dyslipidaemia and delivered a live baby girl weighing 2.4 Kg by spontaneous vaginal delivery at 36 weeks gestation. She conceived her 3rd pregnancy 8 months later which was also carried to term and had a vaginal delivery of a live baby girl weighing 2.55 kg. This report highlights the successful management of pregnancies in KTR and the challenges faced in a poor resource setting.

Blood pressure control among treated hypertensives in a tertiary health institution

BACKGROUND

Goal blood pressure (BP) was defined by the JNC VI and the World Health Organization-International Society of Hypertension (WHO/ISH) as <140 mm Hg systolic and <90 mm Hg diastolic for the general and <130 mm Hg systolic and <85 mm Hg diastolic for special high-risk populations. It is well established that adequate BP control characterizes only a fraction of treated hypertensive patients. The importance of tight BP control has been established in preventing cardiovascular morbidity and mortality

METHODS

We performed cross-sectional studies on the current status of BP control among treated hypertensive in our center. One hundred consecutive patients with essential hypertension who have been attending the out patient hypertension clinic and have been on treatment for at least 6 months were recruited. The pre treatment BP and BP records in the previous 2 visits were noted. Patients were said to have good BP control if their BPs are < 140/90 mmHg (<130/80 mmHg for high risk patients) at the time of the study and in the last visit.

RESULTS

There were 49 males and 51 female (M: F; 1:1), aged 26 to 85 (mean 52.33 +/- 12.29) years. The duration of hypertension ranged 6 months to 30 (mean 7.37 +/- 7.1) years. The duration of treatment in our centre was 6 months to 10 (mean 3.22 +/- 2.23) years. Blood pressure was controlled in 33 (33%) of the patients. Pre-treatment mean blood pressure was significantly higher than the BP value at the time of the study (155.87 +/- 26.02/97.81 +/- 11.89 mmHg versus 143.40 +/- 24.14/86.53 +/- 12.71 mmHg) (p<0.05). Diuretics were the commonest antihypertensive prescribed either alone or in combination (69%), followed by a calcium antagonist (56%) and centrally acting drugs (38%). Twenty seven were on single antihypertensive, 43 (43%) on 2, 25(25%) on 3 and 5 (5%) on 4 classes of antihypertensive. Blood pressure control was associated with taking more than one antihypertensive medication and compliance.

CONCLUSION

Control of BP in patients receiving antihypertensive drugs is still far from optimal in the study population in Nigeria just as in other countries. Many patients had multiple cardiovascular risk factors. Adherence to medication should be encouraged.

Physical exercise and health: a review

BACKGROUND

Physical activity results in increased exercise capacity and physical fitness, which may lead to many health benefits. Individuals who are more physically active appear to have lower rates of all-cause mortality, probably due to a decrease in chronic diseases including coronary artery disease (CAD). This may result from an improvement in cardiovascular risk factors in addition to enhanced fibrinolysis, improved endothelial function, decreased sympathetic tone, and other yet undetermined factors.

METHODS

We reviewed the literature on physical activity and health with particular reference to the benefits derivable by engaging in regular physical activity. The MEDLINE/PUBMED and bibliographic searches for English language studies were used.

RESULTS

Physical inactivity is now considered a risk factor for Cardiovascular diseases (CVD). Regular exercise results in an increase in exercise capacity and lower myocardial oxygen demand leading to cardiovascular benefits, including lower mortality rates. Physically active individuals suffer from fewer ailments than do less-active individuals. Physical activity reduces cardiovascular risk through lowering of blood pressure, improved glucose tolerance, reduced obesity, improvement in lipid profile, enhanced fibrinolysis, improved endothelial function and enhanced parasympathetic autonomic tone.

CONCLUSION

Physical exercise has many health benefits and the evidence for this continues to accumulate. Health care professionals should incorporate counselling to patients for physical exercise in their daily clinical practice, while health policy makers and community physicians should see to implementation of this at the community level.

Ischaemic heart disease in Aminu Kano Teaching Hospital, Kano, Nigeria: a 5 year review

BACKGROUND

Socio-economic changes and rural urban migration have led to emergence of non-communicable disease including ischaemic heart disease (IHD) and many others. The actual prevalence of IHD in Nigeria is not known. The non communicable disease (NCD) survey sought to determine the prevalence of major risk factors, rather than the prevalence of the disease itself. The prevalence is generally considered low in Nigeria but the current impression about its importance stems mostly from anecdotal reports. We therefore set out to describe the prevalence as well as the spectrum of IHD at Aminu Kano Teaching Hospital, Kano.

METHOD

Between July 2000 and June 2005, we reviewed the prevalence as well as the spectrum of presentation of IHD in Aminu Kano Teaching Hospital. Information was obtained from the medical records of patients in the medical unit of the hospital. Age, sex, diagnosis, risk factors for IHD, other relevant clinical and laboratory data and outcome of patients for myocardial infarction (MI) were extracted from the records. Data was analyzed using SPSS version 10.0 software.

RESULTS

There were 5124 medical patients admitted over the period under review, out of which 1347 had cardiovascular diseases. Forty six patients were diagnosed to have IHD giving it a prevalence of 0.9% of medical conditions and 3.4% of all cardiovascular cases. There were 33 males and 13 females (M : F = 2.5:1). Twenty two patients (47.8%) had myocardial infarction, 14 (30.4%) had ischemic cardiomyopathy and 10 (21.7%) had angina. The patients consist of 41 (89.1%) Nigerians, 3 (6.5%) Lebanese, 1 (2.2%) Indian and 1 (2.2%) Pakistani. The risk factors found were Hypertension in 37 (80.4%) of patients, diabetes in 16 (34.8%), and Dyslipidaemia in 20 (43.5%). Others were cigarette smoking and obesity.

CONCLUSION

IHD is an important cause of morbidity and mortality in our population. There is need for us to be on the alert and prepare ourselves to manage these cases. Focus should be on preventive cardiology.

Post transplant Kaposi's sarcoma among Nigerians: a report of two cases

With the establishment of kidney transplant centres in Nigeria and increase in the number of kidney transplant recipients returning home for follow up after successful transplant abroad, an increasing number of patients with post transplant complications are likely to be seen. There is the need for physicians vested with the care of these patients to be aware of the post transplant complications so that early diagnosis and effective treatment can be instituted so as to save both the patient and the allograft. Two out of seventeen renal transplant recipients followed up in our unit had post renal transplant Kaposi's sarcoma. Both were successfully treated with withdrawal of cyclosporin, reduction of other immunosuppressives and introduction of low dose Mycophenolate Mofetil (MMF). One had a course of radiotherapy followed by weekly intravenous vincristine and the other only had vincristine with complete remission of the lesions in both patients. Post transplant Kaposi's sarcoma occurs in Nigerian transplant patients and this report highlights the need for increased awareness and high index of suspicion of post transplant Kaposi's sarcoma among kidney transplant recipients.

Opportunistic infections of the central nervous system in children with HIV infection: report of 9 autopsy cases and review of literature

Central nervous system (CNS) abnormalities attributed to direct effects of HIV infection are seen in most of children with acquired immunodeficiency syndrome (AIDS). Secondary CNS infections with opportunistic and common pathogens are infrequent in this age group. We report 9 cases of opportunistic infection of the CNS found among 65 autopsy cases of pediatric AIDS. These included 4 cases of cytomegalovirus (CMV) infection, 1 of which was associated with aspergillosis, and 2 cases of candidiasis, 1 of which coexisted with Mycobacterium avium intracellulare (MAI) infection. There were also 2 cases of leptomeningitis, 1 due to Mycobacterium tuberculosis (MTB) and the other to Cryptococcus neoformans. In 1 child progressive multifocal leukoencephalopathy (PML) coexisted with mycotic encephalitis caused by an Aspergillus sp.
